Hyperinflation: control of functional residual lung capacity.
Hyperinflation is the consequence of a dysbalance of static forces (determining the relaxation volume) and/or of the dynamic components. The relaxation volume is determined by an equilibrium between the elastic recoil of the lungs and of the chest walls. The dynamic components include the pattern of breathing, upper airway resistance and postinspiratory activity of inspiratory muscles. The resp...
متن کاملReference Values for Residual Volume, Functional Residual Capacity and Total Lung Capacity
Reference values play an important role in establishing whether, in an individual, measured volumes fall within a range to be expected for a healthy person of the same sex, similar stature, age, and other characteristics. Hence, reference values should be chosen that are appropriate to the person being investigated. Ideally, the reference values should be consistent; in the context of this pape...
متن کاملThe Correlation between Lung Sound Distribution and Pulmonary Function in COPD Patients
BACKGROUND Regional lung sound intensity in chronic obstructive pulmonary disease (COPD) patients is influenced by the severity and distribution of emphysema, obstructed peripheral airways, and altered ribcage and diaphragm configurations and movements due to hyperinflation. Changes in the lung sound distribution accompanied by pulmonary function improvements in COPD patients were observed afte...
متن کاملCorrelation between anemia and functional/cognitive capacity in elderly lung cancer patients treated with chemotherapy.
BACKGROUND Elderly cancer patients are often excluded from clinical trials and no data are available on the impact of chemotherapy-related anemia on their functional status and cognitive functions. This observational study investigates the association between hemoglobin (Hb) level and comprehensive geriatric assessment (CGA) variables (MMSE, ADL/IADL, GDS, CIRS and VAS). PATIENTS AND METHODS ...
متن کاملMeasurement of Functional Residual Capacity of the Lung Before and During Acute Lung Injury
Background: We measured Functional Residual Capacity (FRC) of the lungs with a CO2 partial rebreathing technique, first in a mechanical lung analog, and then in mechanically ventilated animals before, during, and subsequent to an acute lung injury induced by oleic acid. We compared the FRC from partial CO2 rebreathing with those of a nitrogen washout reference method. Materials and Methods: Usi...
